"PICTU RE POST-CARD, 84c.

SPECIFICATION forming part of Letters Patent No. 722,711, dated March 17, 1903.

Application filed March 11, 1902. $erial No. 97,800. (No modeld T ctZZ whom it may concern:

Be it known that I, ALFRED J Assn, a subject of the Emperor of Germany, residing at 35 Bornestrasse, Frankfort-on-the-Main, Germany, have invented certain new and useful Improvements in Picture Post-Cards and the Like, of which the following is a specification. Thisinvention relates to picture post-cards; and it has for its object to provide an article formed of two cards between which mechanism is inserted operated by altering the relative position of the two cards forming the walls of the picture post-card under my invention. Motion of the walls by pressing the same together, for instance, induces a current of air acting on a musical reed or the like.

In the accompanying drawings, which illustrate one modification of my invention, Figure 1 is a longitudinal section. Figs; 2 and 3 are respectively back and front views of a post-card containing my improvements.

The post-card consists of two walls, of which one (lettered a) isintended for the address and is formed with a concavity, while the other wall, b, contains the text or a pictorial figure and lies flat. On the interior of the wall I), which in the present case carries the representation of a head and shoulders, the eyes it being cut out and the mouth formed by a slit 2', is a smallwooden plate 0, having a perforation f,covered by a metal tongue or lip e or the like, The perforation f registerswith an opening d in the wall I), as indicated in the drawings, and a spiral spring g is inserted between the wooden plate 0 and the wall a. Moreover, on the wall a is arranged a leaf-spring k, carrying a wooden plate Z or the like, which it presses against the wall b. Upon said wooden plate the eye-pupils and a colored strip in. are? secured, the latter projecting through the slit 0;, Figs. l and 3. The two walls a and b are joined, so that the inclosed space is air-tight. If one brings the two walls a and I) together by pressing them betweenv the hands in the direction of the arrows, the air between the walls will seek an outlet through the opening f and through d, the openings h h andi being closed, as will be shown later. The air must also when passing through the side opening f cause the tongue e to vibrate, and, according to the form of the said tongue, a definite note or call may be produced, as in a harmonica. Upon pressing walls a I) together the leafspring is extended, so that its plate Z moves ing the pressure on the walls the spiral spring I g separates the same, so that fresh air quickly enters through the various openings. The nature and formation of the moving parts and of the sounding parts depends upon the subject of the pictorial representation, and the embodiment illustrated is only given as an example. The invention also may be applied to cards, printed matter, samples, and the like.

What I claim, and desire to secure by Let ters Patent of the United States, is-

1. The combination of the front and rear walls, a pictorial representation on one wall, apertures therein, a plate in rear of said wall adapted to close said apertures, and a spring attached to said plate adapted to hold it in position and cause it to slide when the walls are pressed together, substantially as described. v

2. In combination, the front and rear walls, a pictorial representation on one wall provided with apertures, a plate in rear of the apertures, a spring connecting said plate with the other wall, an apertured plate between the walls, a tongue over the aperture, and a spring interposed between the walls for separating them, substantially as described.

3. The herein-described post-card comprising in combination a fiat card, a concave card of the same dimensions united so as to hermetically form an inclosed space with the first card, an opening in the flat card, a small wooden plate covering said opening, a spiral spring pressing said wooden plate against the flat card, an opening in said wooden plate registering with the opening in the flat card, a tongue, reed opposite said opening, slits serving as eyes and mouth of a figure on the flat card, a wooden plate in the interior and a leaf-spring causing on its extension said plate to traverse closing said slits, eye-pupils formed on said plate and a strip serving as a tongue, as and for the purpose set forth.'

In testimony whereof I have hereunto set my hand in the presence of two witnesses.

JEAN GRUND, BERNHARD KAISER.
